When the bible is VERY CLEAR on both how, when and where to worship God.
Skeptics have an ENDLESS supply of weapons to use against Christianity and they are supplied with it by Christians IN NAME ONLY doing what they do best......living in disobedience to the word of God, doing their Religious thing instead of BEING what God wants!
It is not the vast amount of evidence that skeptics pool their resources but from the even bigger well of hypocrites. It is the hypocrite that wrongly gets credit by the skeptic for Christianity not the true believer who lives out the principles of Christ, so that alone taints the skeptics results completely.
How can you properly see the results if everything you believe about Christianity is based upon the false belief of unbelievers?
Nothing in history is more false than man-made Religion, a mirror NOT OF THE WAYS OF GOD but of man's made up ideas of the ways of God. Man filling in the blanks of his LACK of knowledge about God and then claiming it to be Revelation from God. The Only way to know God is to know his word, if what you know is not grounded upon scripture then its false and that is what 90% of Religion is based in!
